Input Characteristics
The power supply operates within an input range of 90 to 264Vac and a frequency range of 47 to 63Hz. It has a maximum input current of 5A at 115Vac and 3A at 230Vac, with no damage from inrush current.

Specifications
The operating temperature range is 0°C to +50°C at full load, with storage and shipping temperatures ranging from -20°C to +80°C. Humidity tolerance is 5% to 90% during operation and 5% to 95% during storage. The dielectric withstand is 1800V AC for 1 second. Efficiency is at least 80%, with a rise time of less than 20ms and a hold-up time of at least 17ms at nominal input voltage. The power good signal has a power-on delay time of 100 to 500ms and an off delay of at least 1ms. Leakage current is less than 3.5mA at 264Vac, 50Hz. The MTBF is 100,000 hours at maximum load and +25°C. Dimensions are 150x81.5x40.5mm.

Output Characteristics
The power supply provides various output voltages with specific load regulations and ripple & noise levels. The total output for +12V1 and +12V2 should not exceed 18A, and the combined output for +3.3V and +5V should not exceed 130W. The total power output is 270W.

Features
The power supply complies with Flex ATX and ATX12V standards and includes active power factor correction meeting EN61000-3-2. It is high efficiency, reliable, and compliant with the European Union Directive 2002/95/EC. It features a remote ON/OFF function, an internal 12V DC fan, and a thermal fan speed control function for noise reduction. It includes protections against over voltage, short circuit, and over current, and is 100% Hi-pot, ATE, and burn-in tested. It has a re-settable power shutdown and complies with FCC part 15 subpart J class B and CISPR 22 class B standards. It is approved by CUL/UL60950-1, TUV EN60950-1, NEMKO EN60950-1, CE, BSMI, and FCC.
